A continuous femoral nerve block leads to better analgesia, less morphine consumption and less morphine-related side effects after TKA. Early functional recovery is improved, resulting in more patients reaching 90 degrees knee flexion after 6 days. However, after 3 months, no significant functional benefits were found.
Patients with Morquio syndrome possess a number of characteristics which may complicate an anaesthetic procedure. The most important is that a deposition of mucopolysaccharides in the soft tissues of the oro-pharynx distorts the airway, making the airway management difficult, while the atlanto-axial instability puts these patients at risk of subluxation and quadriparesis. As the endotracheal intubation in Morquio syndrome patients may be difficult or even impossible, we recommend the technique of awake fiberoptic intubation to be considered. Our approach to awake fiberoptic intubation in an adult patient is described in this case report.
Background and Aims:Pain reduction is important for rehabilitation after total knee arthroplasty. Intra- and peri-articular infiltration with local anesthetics may be an alternative to commonly used locoregional techniques. Adding pregabalin orally and s-ketamine intravenously may further reduce postoperative pain.Material and Methods:This prospective, randomized, double-blind, placebo-controlled study compared two methods of perioperative analgesia. Control patients received a standardized multimodal postoperative analgesic regime of paracetamol, diclofenac, and piritramide-patient-controlled analgesia, including ropivacaine knee infiltration during surgery. The study group received pregabalin orally and s-ketamine intravenously as an additional medication to the standard multimodal regimen. The control group received placebo.Results:The study group showed lower piritramide consumption during the first 24 h (P: 0.043), but with more side effects such as diplopia and dizziness.Conclusion:Addition of pregabalin and s-ketamine resulted in lower piritramide consumption during the first 24 h postoperatively. However, more investigation on benefits versus side effects of this medication is required.
The varying baseline temperatures across the trunk, the limited sympathetic block-induced increase in skin temperature at the trunk and the difficult control of influences from the surroundings partly obscured the extent of the skin temperature increase and its correlation to sensory block height. These factors have to be controlled to improve the use of infrared cameras as an easy bedside tool for predicting the cranial extent of (sympathetic blockade during) spinal anaesthesia.
After sciatic nerve block, temperatures of the foot increased significantly. There was a good correlation between pinprick testing and infrared temperature measurement. This makes infrared skin temperature measuring a good test in determining block success when sensory testing is impossible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
